Cavities / Tooth Decay
Although tooth decay has declined among young children as a group, it can still be a problem for individual children, and even teens and adults. That’s because plaque, a sticky film of bacteria, constantly forms on your teeth. When you eat or drink foods containing sugars or starches, the bacteria in plaque produce acids that attack tooth enamel. The stickiness of the plaque keeps these acids in contact with your teeth and after many such attacks, the enamel can break down and a cavity forms.¸
Preventing Decay:
•Brush your teeth twice a day with fluoride toothpaste.
•Clean between teeth daily with floss or an inter-dental brush.
•Eat a balanced diet and limit between-meal snacks.
•Visit your Ottawa Family Dentist regularly for professional cleanings and oral exams.
•Ask your dentist about dental sealants, a protective plastic coating that can be applied to the chewing surfaces of the back teeth where decay often starts.
Aren’t Cavities Just Kid’s Stuff?
•No. Changes that occur with aging make cavities an adult problem, too. Recession of the gums away from the teeth, combined with an increased incidence of periodontal (gum) disease, can expose tooth roots to plaque. Tooth roots are covered with cementum, a softer tissue than enamel. They are susceptible to decay and are more sensitive to touch and to hot and cold. The majority of people over age 50 have tooth-root decay.
•Decay around the edges, or margins, of fillings is also common to older adults. Because many older adults lacked benefits of fluoride and modern preventive dental care when they were growing up, they often have a number of dental fillings. Over the years, these fillings may weaken and tend to fracture and leak around the edges. Bacteria accumulate in these tiny crevices causing acid to build up which leads to decay.
